Anyone know where "System Module" is?

I'm trying to use the "New" system (code) configuration (MCC) stuff in MPLAB X and I receive a hint saying (red oval if it's not obvious),


However, I can't find the System Module, anyone know where it hides? If anymore info required then ask away.

Thanks,

Mike.
Edit, seems I need to set this in the Configuration Bits - not "Source Module". Oh well, at least I found it.
